NEW JERSEY, ASSIGNOR Tb THE SUN TUBE GOR- romrron, or HILLSIDE, NEW JERSEY, A conronerron or NEW JERSEY PAINT ROLLER Application filed March 2Q, 1928. Serial No. 265,685.

This invention relates to paint rollers, and particularly to an improved paint roller for applying paint or a colored coating to collapsible tubes, the object being to provide an 5, improved construction whereby the tube will lapsible tubes wherein the surface is stiff and substantially unyielding, while the body is resilient and yielding.

A further object of the invention is to provide an improved paintroller for applying paint to collapsible tubes wherein a metal surface is formed on the roller for preventing irregularities in the tube from injuring the roller, while causing the roller to correct to a certain extent the tube and apply paint thereto at the same time.

In the accompanying drawings Figure 1 is a fragmentary perspective View showing part of a machine carrying collapsible tubes to be painted and a roller embodying the invention shown associated therewith' Figure 2 is a large horizontal sectional view through the roller shown in Figure 1;

Figure 3 is a transverse sectional view through Figure 2 on line 33.

In the manufacture of collapsible tubes used in carrying toothpaste, Vaseline and other substances, the tubes must be coated or painted to present a pleasing appearance. After the tubes have been formed by any preferred or well-known method they are placed on suitable spindles 1 carried by rotating member 2. The spindles 1 are freely rotatable, though carried by the member 2. As the spindles 1 are moved in a circle on member 2 they pass a coating or paint roller so as to receive a supply of paint or colored matter. Heretofore these paint rollers have been formed 7 of rubber, gum or other soft and yielding material. In the resent instance, the paint or coating roller 3 is of special construction, though used in the same place and in the same manner as the former, rollers. Roller 3 is supplied with paint or colored matter from any suitable source by roller 4. As

. where roller 4 keeps the surface 5 of roller 3 covered a proper coating is transmitted from surface 5 to the various tubes 6 as they pass. Preferably, roller 5 is rotated at a speed which will cause tube 6 to perform one or more revolutions while in enga ement with roller 3. This will insure a goo coating to tube 6. The roller 5 is provided witha band or peripheral member 7 of hard, unyielding material as, for instance, metal- This metal may be steel, copper or other material which will not be injured by the paint or coating material. The outer surface 5 is preferably very smooth and by reason of being hard and unyielding will straighten out to a certain extent any slight bumps or projections on the tube 6 and also will not be cut or injured by any irregularities on tube 6.

In order to take care of different thickness in the tube or take care of other conditions yielding action in roller'3 is desirable, end members 8 and 9 are provided formed of resilient material. If preferred, a system of springs could be used, though it has been found bettercommercially to use rubber disks formed with suitable perforations 10. These rubber disks are cemented or otherwise secured to the peripheral band or body 7 and, if desired, may be I cemented or otherwise rigidly secured to the rotating shaft 11. However, if the central apertures 12 are slightly less in diameter than shaft 11, these end members may be forced over the shaft and by reason of the resilient action of the end members are pinched or held in place by friction. After the roller has been once correctly positioned, as shown in Figure 1, shaft 11 begins to rotate and also member 2 begins to rotate. As member2 begins to rotate either a machine or workman will apply unpainted tubes to the various spindles 1. As the tubes pass the roller 3 they press against the roller and are coated thereby. After leaving the roller 3 either a machine or a workman will grasp the cap or otherwise operate on the tube 6 to remove the same readily for a new tube.

- WhatI claim is:- j

A paint roller of the. character described, comprising a cylindrical metal body and disks of soft resilient rubber at each end formed -with a central shaft-receiving aperture and a plurality of apertures between the center and the outer edge.
